Pre-Charge Resistor is installed in the Power Relay Assembly
(PRA) and it protects the high voltage circuit by limiting the charging
current when the inverter capacitor is being pre-charged.

System Configuration
PAS consists of 8 sensors (4 front & 4 rear) which detect
the obstacles and transmit the result in 3 separate warning levels, the
first, second and third to IPM (BCM) via Lin communication. IPM (BCM)
determines the level of alarm based on the transmitted communicati ...
